DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening method in slope construction using a pressure receiving plate and a pressure receiving plate for stabilizing a slope.

[0002]

2. Description of the Related Art There is a slope-stabilizing pressure-receiving plate which is arranged in a scattered manner at a position of a ground anchor previously cast on a slope, and is fixed so as to press against the ground.

[0003] The slope stabilizing pressure-receiving plate is a concrete structure having a long-term bearing capacity, which contributes to protection and strengthening not only the surface layer of the slope but also the deep layer, and has a shape suitable for the use such as a square or a cross. Is made.

[0004] By the way, it is a common practice to cut the mountainous area and perform reinforcement work to prevent the collapse on the exposed slope, and then to plant trees to increase the natural taste. In the case of using a plate, as shown in FIG. 5 (an example in which a rectangular supporting plate is used in the drawing), the surface area of the pressure receiving plate A 'may be relatively large, so that even if planting is performed in the vicinity, it is sufficient. The reality is that natural beauty cannot be created.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-mentioned pressure receiving plate for stabilizing a slope, and to make the slope where the pressure receiving plate is installed rich in natural taste by tree planting. I do.

[0006]

In order to achieve the above object, the method of the present invention comprises a Y-shape, a cross-shape, a square, a circle, and the like, and a ground anchor is inserted into the center of the inclined surface. On the side that becomes the upper edge of the pressure receiving plate provided with a pressure receiving surface to be fixed to And embankment is performed between the plate-shaped wings and the embankment is planted.

The present invention is further developed as follows: the main pressure receiving plates formed as described above are arranged in series in a horizontal lateral direction at a constant interval, and a plate-like shape protruding from an adjacent main pressure receiving plate. The blades are connected by a separate auxiliary pressure receiving plate, and embankment is performed on the plate-like wings as well as the plate-like wings of the main pressure-receiving plate to plant trees. At this time, construction is performed stepwise in a plurality of rows in the height direction of the inclined surface, or the primary and secondary pressure receiving plates are arranged in a staggered manner in a vertical positional relationship.

The main pressure receiving plate described above preferably has a plurality of reinforcing ribs provided in an upright state between the plate along the inclined surface and the protruding plate-like blades.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing a slope on which a greening method according to the present invention is implemented, FIG. 2 is a cross-sectional view showing a state in which a part of the slope is longitudinally cut, and FIG. 3 is a view showing the present invention. It is a figure showing an embodiment of a main pressure plate and an auxiliary pressure plate for intermediate connection used for it.

First, a main pressure receiving plate A for slope stabilization according to the present invention and an intermediate auxiliary pressure receiving plate B used therein will be described.

A main pressure receiving plate A for stabilizing a slope is composed of a main body 1 which is in contact with the ground surface, and a plate-like wing 2 which is continuously provided on an upper edge portion thereof.
And the whole is integrally formed of concrete or a reinforcing material embedded therein.

At this time, the main body 1 has a bottom surface 3 as a pressure receiving surface pressed against the ground, and a central position provided with an anchor hole 4 for inserting a ground anchor. In the illustrated example, the shape is Y-shaped. However, the shape is not limited to this, and may be, for example, a square (a), a cross (b), a rhombus (c), or a circle (d) as shown in FIG.

The plate-like wing 2 has a certain area and projects to the front and upper part of the main body 1 at a certain inclination angle. 5 is a drain hole provided on the lower edge of the plate-shaped wing 2, 6 is a void formed on the lower surface side of the plate-shaped wing 2, and 7 and 7 are cross-linked between the plate-shaped wing 2 and the upper surface of the main body 1. It is a reinforcing rib.

The intermediate connection sub-pressure receiving plate B is formed integrally with a uniform cross section by concrete or a reinforcing material embedded therein, and has various lengths for connecting the plate-shaped blades of adjacent main pressure receiving plates. Things are designed and prepared. In the illustrated example, the plate-like wing 2
In order to correspond to the shape of the left and right end surfaces, the cross-section is formed in an elliptical shape, and a notch 8 is provided at the left and right end edges so as to be able to be locked in a superposed state. In addition, p is a drainage hole provided in the sub-pressure receiving plate B.

Next, an example of slope stabilization work using the above-described slope stabilizing pressure receiving plate will be described.

FIG. 2 is an explanatory sectional view showing an outline of the above construction, wherein S is a slope, and 9 is a ground anchor which is driven into the rock of the slope S so as not to come off.

The ground anchor 9 is projected from the anchor hole 4 of the main pressure receiving plate A, and the upper end thereof is fixed using a fastener 10 in a state where a tensile force specified by a design calculation is applied.

The above operation is carried out in a serial arrangement at an appropriate interval in the horizontal direction of the slope surface, and is also carried out in a stepwise manner at an appropriate interval in the height direction so as to be arranged in parallel. At this time, it is preferable that the positional relationship of the main pressure receiving plates A in the vertical direction is staggered.

In this state, the main pressure receiving plate A is in a state where its bearing surface is pressed against the slope s by an appropriate force. Therefore, not only the surface layer of the slope s but also the entire slope including the deep rock is protected and reinforced. And stabilized over time.

Next, an example of the greening work of the slope s which is stabilized by the main pressure receiving plate will be described.

As shown in FIG. 1, a sub-pressure receiving plate B is bridged between the adjacent plate-shaped blades 2 of the main pressure-receiving plate A, and the sub-pressure receiving plate B and the plate-shaped blade 2 are arranged in a horizontal row. Is formed. At this time, the end of the sub-pressure receiving plate B is positioned in an overlapping relationship with the end of the plate-like wing 2.

Subsequently, soil or fertilizer is put into the space between the plate-like wing 2 and the sub-pressure receiving plate B of the main pressure receiving plate A and the slope s to form a planting floor 11, and a suitable place is provided at this location. They do some kind of tree planting. In the drawing, reference numeral 12 denotes earth retaining plates installed at both ends of the planting floor 11.

Tree planting according to the above is akamatsu, hayabaya,
And than the ones such as seedlings or Sasane such confectionery can be easily planted, conventional mosquito net, the greening effect compared to those planting seed plants due mugwort and Medohagi becomes extremely high.

In the above embodiment, an example is shown in which the slope s is stabilized and greened. However, the present invention is not limited to this, and can be applied to any slope.

[0025]

According to the present invention described above, a very effective tree planting can be performed on the slope where the pressure receiving plate is installed. In other words, since the plants are planted in a stable horizontal state, they can grow well at the same time as having good survival, and can be effectively greened.

In particular, a continuous horizontal row of trees can be easily planted, and according to the second and third aspects, each pressure receiving plate can be made inconspicuous with respect to the entire inclined surface. What is described in Claims 4 and 5 is Claim 1,
It is excellent in that the methods described in 2, 3 can be carried out simply, safely and firmly.
